A 3D Magnetohydrodynamics (MHD) arc model in conjunction with an arc movement model is applied to simulate the arc rotation as well as to solve its effect on the pressure in an auto-expansion circuit breaker. The rotation of the arc driven by an external electromagnetic force is simulated in the case with 200 kA of the short circuit current and 16 ms of arc duration. The arc rotating process and the speed of arc rotation have been obtained in the simulation. A comparison of the pressure in the expansion volume with and without an external magnetic field has been carried out based on the calculation results of two cases. The results of the simulation reveal that the arc rotation, which causes more energy exchange between the arc and its surrounding gas, can evidently bring about the pressurization in the expansion volume, which would contribute to more effective arc quenching at current zero and further reducing operation power.

“…Various mathematic arc models have been developed and applied to arc interruption simulation for MCCBs and MCBs [1][2][3][4][5][6][7][8]. However, it is still a challenge to develop an appropriate numerical simulation method for arc interruption process to describe the arc motion gas dynamics in MCCBs and MCBs.…”

Mathematic equations describing arc root movement on different geometries of contact surfaces for low-voltage circuit breakers are proposed in this paper. Coupling with a chain-type arc model and considering mechanical movement, magnetic field and electrical transient circuit, an arc interruption numerical model for low-voltage circuit breakers has been developed. Based on this model, the arc motion during interruption process for low-voltage circuit breakers was simulated. The paper also analyzes the arc motion characteristics in different configurations of arc runners.
